Title: Pressure regulator for plant handling highly corrosive fluid
Inventor: MIYAKE TAKASHI
IPC: G21D3/00
Filed: 1980-07-04
Abstract: PURPOSE:To stably and exactly control the pressure of a reactor by a method in which a pressure-inducting pipe is provided between a pressure regulating chamber and the reactor, noncorrosive fluid is filled in the pressure regulating chamber side, and highly corrosive fluid is filled in the reactor side. CONSTITUTION:In a plant handling a highly corrosive fluid, an almost N-shaped pressure-inducting pipe 13 is provided by connecting two U-shaped pipes between the bottom of a pressure regulator 12 with a heater and a pressure regulating meter and the inlet side of a reactor 10. And, a noncorrosive fluid, e.g., air, having a smaller density than that of a highly corrosive process fluid 11 and also incapable of mixing with the fluid 11 is filled in the pressure regulating chamber side of the pressure-inducting pipe 13, and also a highly corrosive process fluid 11 is filled in the reactor side. Thus, the pressure of the pressure regulator 12 is transmitted through a liquid 16 and fluids 15 and 14 to the process fluid 11, and the pressure of the process fluid 11 is therefore regulated stably and exactly.

Title: Nonlinear optical material
IPC: G02F1/35
Filed: 1991-03-28
Abstract: PURPOSE:To provide an organic nonlinear optical material of excellent transparency in a visible area and crystallinity without large reverse symmetric center in the secondary nonlinear optical effect by forming this nonlinear optical material of a specific urea derivative. CONSTITUTION:This nonlinear optical material is formed of an N-alkyl-N'-(4- nitrophenyl) urea derivative expressed by a formula. In the formula, R represents an alkyl group of a deuterium-substituted alkyl group. As the alkyl group, a methyl group, an ethyl group, an n-propyl group, an iso-propyl group, n-butyl group, a sec-butyl group, an iso-butyl group or a tert-butyl group functions effectively. This N-alkyl-N'-(4-nitrophenyl) urea derivative can be obtained by reacting nitrophenyl isocyanate, for instance, and alkylamine or an aqueous solution equivalent to R with acid or a base as a catalyst. The symmetric property is thereby lowered, and the nonlinear optical material can be converted into active material to secondary nonlinear optical effect in a wide wavelength area.

Title: Method and device for recovering of developer
Inventor: SAITOU KIKUO
IPC: G03G21/00
Filed: 1979-07-16
Abstract: PURPOSE:To make possible the removal of foreign matter from the used toner by applying an electric field between a capturing roller and a receiving roller and selectively scattering the used toner on the capturing roller to the receiving roller. CONSTITUTION:A capturing roller 1 and a receiving roller 2 are disposed and a DC electric power source 4 is connected. The spent toner falls onto a duct 9 and is accumulated on the roller 1. When DC voltage is applied between the rollers 1 and 2, the toner charged negative causes a scattering phenomenon and sticks on the peripheral surface of the roller 2. The coarse and fine power toners are suppressed of scattering. The most of the dusts such as paper dusts are larger than ordinary toner grain sizes 7-15mu. It is possible to scatter the reusable toner selectively to the roller and recover the same by controlling the layer thickness of the toner on the roller 1, the spacing between the rollers 1, 2 and the applied voltage.

Filed: 1993-04-20
Abstract: PURPOSE:To prevent mis-judgement and erroneous processing even at the time of sucessively receiving erroneous distribution cells by adding a counter SNE and monitoring the continuity of the sequence numbers of reception cells. CONSTITUTION:At the time of receiving a normal cell, counters SNR and SNE are counted up and the counts of both are coincident with SN sequence number) (0) of the reception cell. When SN (0) and SNR become noncoincident at a multiple step, a stored cell is outputted in the cases of DCN(-1)=0 and DCN(0)=1 but counting is stopped to hold a right SR value. When SN and stored SN are successively discontinuous, the cell is judged to be an erroneous distribution cell and the stored cell is discarded. When signals SN and SNE are coincident, the received cell is judged to be the normal cell and the stored cell is discarded so as to restart the counting of SNE to make SNR coincident with SN. At the time of DCN=0, cell discard is judged, the stored cell is outputted and SNR and SNE are made coincident with SN(0). When SN(0) and SNR are coincident, SN(-1) is outputted to a signal processing part to be reread as DCN(0)=0.
